This invention relates to improvements in latter utilized as a support for a part of the or modifications of the chassis framing for vehicle steering gea vehicles, more particularly for motor ve- Fig. 8 is a transverse cross section along hicles, having girders composed of flat sheet the line IJ of Figure 2 showing the conmetal plates welded together, the size of the nection between a longitudinal and trans- 60 said plates being graduated to correspond to Verse girder. the loads which the walls havev to support.

Referring to Figures 3 an i 4;, the same 90. The invention also consists inthe i illustrate the use of a stiffening member 9, proved construction of chassis frame as hereas a support for one of the rear main springs mbefore more particularly described with through the intermediary of a bolt 11. passing 3 reference to the accompanying drawings, in r gh It nd side plates i '5 The side 4 which, sheet plates 1 and 2 of the longitudinal 05 Figures 1 and 2are respectively a sectional "irder a, are formed with holes to receive elevation and a plan view of the improved e f ning m m er 9 and are provided chassis frame, with internally projecting flanges 3, 4, the Fi res 3 and 4 are respectively a'secsaid stiffening member g projecting beyond tiona elevation and a transverse section of the sides of the girder andbeingsurrounded 100 the rear s ring support taken along the line y thicker plates 5, 6 having flan es 7, 8, AB in igure 2 and along the line C-D the edges of which are welded onto t e edges in Figure 1, of the metal strips of the girder (2,. The

Figures 5 and 6 are similar views of the edges of the inner flanges 9, 10 of the plates front spring support taken along the line 5, 6 are made flush with the edges of the 105 E-F of Figure 2 and along the line G-H tubular member g of Figure 1 respectively, and Referring to Figures 5 and 6 which illus- Figure 7 is a transverse section through trate the use of a stiffening member as a one of the longitudinal girders in the plane support for one of the front main springs, of one ofthestlfiening members showing the the tubular stiffening member 9 is recessed 0 at its lower end to allow the end 7' of the spring to be introduced therein and be attached to a bolt is which passes through the said stiffening member and is surrounded by a sleeve 70,. The bolt is is supported on plates 5, 6 which are constructed in the manner described with reference to Fi res 4 and 5, with the exception that they. t inside the tubular stifl'ening member, instead of being mounted outside the same. The edges of the external flanges 7, 8 of the plates 5, 6 are welded onto the edges of the stiffening member 9 and onto the edges of flanges 11, 12 formed on the side metal strips 1, 2 of the girder (1 Referring to Figure 7 which illustrates a stiffening member 9, serving as a bearing for the toothed sector used in connection with the steering column, the shaft m of the toothed sector is mounted in a bearing formed by the tubular member 9 which is welded at its edges onto the two opposite metal strips of the girder a Figures 1 and 2 also show other stiffening or relnforcing members. Thus 9 is a tubular stiffening member provided in the transverse girder (Z and serving for the passage of the crank handle. Further f f f f, are boxes of sheet metal welded onto the girders and serving for the purpose of increasing the moments of inertia of the whole of the structure and at the same time serving as supports or attachments. Figures 1 and 2 also show plate-like stiffening members Z Z Z 1,, which are welded onto the surfaces of the longitudinal and transverse girders a a d 0 at their points of connection wlth one another. The said plates are substantially T-shaped and provided both on the upper and on the lower surfaces of the. girders, as shown in Figure 7.

I wish it to be understood that the invention is not limited to the details of construction hereinbefore described with reference to the accompanying drawings, as the same may be modified in various respects without in any way departing from the spirit of the invention. This for instance although the stiffening members have preferably been verse girders at the shown hollow or of tubular shape and such as to be capable of being utilized also for other purposes, the may be made entirely solid instead of ho low and be arranged to connect the upper with the lower plates of the irders instead of or in addition to connecting the side plates thereof.

What I claim 1s: J

1. A chassis framin for vehicles having girders composed of at sheet metal plates welded together and stiffening members connecting opposite sheet metal plates of the indivi ua girders, for the purposes set forth.

2. A chassis framing for vehicles as. claimed in claim 1 and in which the stiffening members are arranged near the support" ing points of the chassis framing.

3. A chassis framing for vehicles as claimedlin claim 1 and in which the stiffening members are made hollow, for the purposes set forth.

4. A 'chassis framing for vehicles as claimed in claim 1, in which the stiifening members are made hollow and some of them serve as supports for the -main springs of the chassis framing, as set forth.

-5. A chassis framin for vehicles having girders composed of at sheet metal plates welded together, one of the girders havingv a hollow stiffening member serving as a self contained bearingifor wholly supporting the toothed sector used with the steering column of the vehicle as set forth.

6. A chassis framing for vehicles having hollow double TT'longitudinal and transverse girders composed of flat sheet metal plates welded together and substantially-1'- shaped reinforcing plates facially applied upon the top and bottom of the longitudinal and transverse girders and welded along their edges onto the longitudinal and transomts where'the said girders are connecte together 'to prevent weavingof the chassis. 1

Intestimony whereo'f-I have signed my name to this specification.
